Frequently asked questions

Can AI agents send emails through SendGrid?+

Yes. Define a sendEmail action with recipient, subject, and content inputs. Use dynamic templates for consistent formatting. Agents can trigger transactional emails based on workflows.

How do I prevent email spam from AI agents?+

Use SendGrid sender verification, implement daily send limits in your actions, require confirmation for bulk sends, and monitor bounce rates. SendGrid also provides built-in compliance features.

Templates are strongly recommended. They ensure consistent branding, are easier to manage, and let agents focus on dynamic content (recipient, personalization) rather than layout.
